I don't know. It just occurred to me that I hardly ever see black buys with straight hair these days. Everyone at my church is black except me and two other guys, and none of the guys have straight hair. Everybody's either natural, bald, or has dreads. It's an odd thing now that you mention it. All the women have weaves, wigs, braids, or dreads, and none are natural, and all the guys are the opposite.
